Line Source Speakers
A line source is a vertical array of a theoretically infinite number of point source drivers.
This configuration has a number of desirable characteristics for sound reproduction in enclosed spaces, especially in large environments. It allows sound to propagate over long distances, actually providing increased sound reinforcement and level equalization, the further you are from the loudspeaker itself. In practice, it is almost impossible to detect any change in volume level and audio quality from the front to the rear of the room. Having a powerful sound pressure level (SPL) at the back of the theater will not consequently have higher SPL at the front seats.
As a line source consists of many drivers the load on each driver is consequently much lower than it would be, if one conventional point source were required to deliver the same sound pressure. This drastically reduces distortion and power compression will be non-existent. As the individual drivers operate far below their power limit, dynamic headroom is retained, even at extremely high sound pressure levels.
The dispersion pattern of a line source is not spherical like that of a point source, but cylindrical as it extends outward from the loudspeaker. This dispersion pattern eliminates energetic first reflections from the ceiling and floor. Floor and ceiling reflections are the most common obstacles in achieving crystal clear dialogue. This also eliminates distracting room reflections resulting in the system’s exceptional imaging capabilities.
